Definitions

  • the present invention relates to a spray bar suspension device for an agricultural vehicle, and an agricultural vehicle equipped with such a device.
  • FIG. 1 diagrammatically shows a top view of a spray bar suspension device of the state of the art.
  • arrow A indicates the direction of travel of the agricultural vehicle E equipped with the device.
  • the suspension device comprises a stationary frame 1 secured on the vehicle E, a right bar holder 3 and a left bar holder 5 both pivotably mounted on the stationary frame 1 , and right 7 and left 9 spray bars mounted stationary on said respective holders.
  • This folded position in particular allows the agricultural vehicle to travel on the road.
  • a constant problem observed of the state of the art is the oscillating movement of the spray bars 7 , 9 , in particular in certain situations such as turns, braking and acceleration of the vehicle E: this is traditionally referred to as a “whiplash effect.”
  • a slide 15 is inserted between the two cylinders 11 and 13 , which can slide on the stationary frame while being returned to a central equilibrium position by elastic elements such as a spring 17 .
  • This device of the prior art allows pivoting with elastic return of the holders 3 , 5 and therefore the associated bars 7 , 9 both toward the front and the rear of the vehicle E, without phase lag.
  • compression springs 19 , 21 are respectively inserted between the cylinders 11 , 13 and the stationary frame 1 .
  • the device of the prior art shown in FIG. 4 results from a combination of the two previous devices, and thus comprises not only a slide 15 elastically returned to its equilibrium position by the spring 17 , but also compression springs 19 and 21 inserted between said slide 15 and the respective cylinders 11 , 13 .
  • This device of the prior art allows rotations of the bars 7 , 9 both toward the front and the rear of the vehicle E, and a phase lag in the time of the oscillations of those two bars, in particular during turns, braking, acceleration of the vehicle E.
  • the present invention aims to provide a spray bar suspension device for an agricultural vehicle making it possible to improve the damping of the oscillations of the two spray bars, with respect to the devices of the prior art described above.
  • a spray bar suspension device for an agricultural vehicle comprising a stationary frame, a right bar holder and a left bar holder that are pivotably mounted on said stationary frame, and damping elements inserted between each of said holders and the stationary frame, remarkable in that said damping elements comprise:
  • the present invention also relates to an agricultural spray vehicle, remarkable in that it is equipped with the device according to the preceding, supporting spray bars mounted on said holders.
  • FIGS. 1 to 4 diagrammatically describe different spray bar suspension devices for an agricultural vehicle of the prior art, described in the preamble of the present description
  • FIG. 5 diagrammatically shows a spray bar suspension device for an agricultural vehicle according to the present invention, in the idle position
  • FIG. 6 shows this device during a left turn with a relatively low acceleration
  • FIG. 7 shows this device in a left turn situation with a relatively significant acceleration
  • FIG. 8 shows this device in a braking situation of the agricultural vehicle
  • FIG. 9 shows this device just after braking
  • FIGS. 10 and 11 are respectively similar to FIGS. 8 and 9 , for an acceleration situation of the agricultural vehicle.
  • FIG. 5 shows that the suspension device according to the invention comprises a stationary frame 1 , on which a right holder 3 and a left holder 5 are pivotably mounted, right 7 and left 9 spray bars respectively being mounted in a stationary manner on those two holders.
  • Damping elements are provided between said two holders and the stationary frame 1 , as will be described below.
  • damping elements comprise right 23 and left 25 rotational supporting elements mounted secured on the stationary frame 1 , said supporting elements being able to assume the form of balls or cylinders.
  • a right structure 27 is articulated on a right actuating cylinder 29 , which in turn is articulated on the right holder 3 .
  • a left structure 31 is articulated on a left actuating cylinder 33 , which in turn is articulated on the left holder 5 .
  • the right structure 27 includes two right 35 and left 37 clevis mountings fitting the shape of the respective supports 23 and 25 , and extending over substantially one quarter of the circumference of those supports.
  • the left structure 31 includes right 39 and left 41 clevis mountings, fitting the shapes of the respective supports 23 and 25 , and extending over circumference quarters of said supports, in a manner complementary to the clevis mountings 35 and 37 of the right structure 27 .
  • Two primary compression springs 43 and 45 are inserted between the right structure 27 and the stationary frame 1 .
  • two other primary compression springs 47 and 49 are inserted between the left structure 31 and the stationary frame 1 .
  • secondary compression springs 51 and 53 are inserted, on the right and on the left, respectively, between the right structure 27 and left structure 31 .
  • FIG. 6 in which arrow A indicates that the agricultural vehicle E equipped with the device according to the invention is turning to the left, with a low acceleration.
  • the right bar 7 located outside the turn, tends to remain at the rear of the vehicle, and therefore to pivot in the clockwise direction, as shown in FIG. 6 .
  • the left secondary spring 53 is compressed, but not enough to cause movement of the left structure 31 , in light of the relatively low acceleration involved.
  • the right clevis mount 35 of the right structure 27 then bears on the right support 23 , thereby allowing a rotation of the right structure 27 around said right support 23 .
  • the primary springs 43 , 45 as well as the secondary spring 51 are then compressed, and it will therefore be understood that a movement with rapidly damped oscillations of the right bar 7 around its equilibrium position is established.
  • the speed of the damping is procured by the combined effect of the primary springs 43 , 45 , the secondary springs 51 , 53 , and the tilting of the holder 27 from one to the other of the rotational supports 23 and 25 .
  • phase lag of the right 7 and left 9 bars that can be seen in FIG. 7 , through which the left bar 9 returns toward the rear of the vehicle E while the right bar 7 returns toward the front of said vehicle E, and vice versa, makes it possible to cancel out the energies transmitted to those two bars.
  • the springs 43 , 45 , 47 , 59 , 51 are compressed by different degrees, the spring 53 being relaxed.
  • the left clevis mount 37 of the right holder 27 moves away from the left support 25 , such that the right holder 27 pivots around the right support 23 .
  • the two bars 7 and 9 tend to move toward the front of the agricultural vehicle E, as shown in FIG. 11 , thereby compressing the right secondary spring 51 and relaxing the left secondary spring 53 .
  • the suspension device according to the invention allows very effective dissipation of the energy transmitted to the spray bars by the various accelerations of the agricultural vehicle bearing them.
